Python Not Opening Image Files

Code:
import turtle as trtl
wn = trtl.Screen()
wn.setup(width = 1.0, height = 1.0)
wn.bgpic("Underseav2_BG.png")
wn.mainloop()
Error Message:
Traceback (most recent call last):

_tkinter.TclError: couldn't open "Underseav2_BG.png": no such file or directory
This is the Code I wrote and the error message I got. I have the image file in the same folder (shown in this image here:[Code&Folder]
as my code, yet Python says they are not in the same directory. What has happened here, and is there anything I can do to fix it?
Thanks!

If you download the image from the Internet, make sure that its original format is png.
If you download the image as a jpg and modify it to png, I think this will not work.

I downloaded an image from this site in png format, the code worked successfully.

if you're using Mac, right click -> Quick Actions -> Convert Image -> Choose the Format to "PNG"

hey ,i have created a program in gui tkinter in python and couldnt upload image as label/icon eventhough they are under same project

from tkinter import *
window = Tk()
window.geometry("500x500")
icon = PhotoImage(file="X.png")
window.iconphoto(True,icon)
window.mainloop()
#my code
#error
Traceback (most recent call last):
File "C:\Users\priya\PycharmProjects\pythonProject2\main.py", line 5, in <module>
icon = PhotoImage(file="X.png")
File "C:\Users\priya\AppData\Local\Programs\Python\Python310\lib\tkinter\__init__.py", line 4093, in __init__
Image.__init__(self, 'photo', name, cnf, master, **kw)
File "C:\Users\priya\AppData\Local\Programs\Python\Python310\lib\tkinter\__init__.py", line 4038, in __init__
self.tk.call(('image', 'create', imgtype, name,) + options)
_tkinter.TclError: couldn't recognize data in image file "X.png"

It seems that the file X.png is not a valid PNG image file, try viewing it in a image viewer and check its filetype via https://www.checkfiletype.com/ or using the file command via WSL.

Imaging problems with Python 3.6

I am creating artificial intelligence to play Chinese checkers with Python, but I can't even get an image of a board to show up!
I am using this code:
from tkinter import *
root = Tk()
board = PhotoImage(file="board.ppm")
root.mainloop()
I get the following error:
Traceback (most recent call last):
File "/Users/GAMEKNIGHT7/Desktop/genius hour/chineseCheckersAI(genius hour).py", line 3, in <module>
board = PhotoImage(file="board.ppm")
File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/tkinter/__init__.py", line 3539, in __init__
Image.__init__(self, 'photo', name, cnf, master, **kw)
File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/tkinter/__init__.py", line 3495, in __init__
self.tk.call(('image', 'create', imgtype, name,) + options)
_tkinter.TclError: couldn't recognize data in image file "board.ppm"
I placed the code file in the same file as the image. What happened? How can I fix it?

Try running the following in Terminal:
file board.ppm
If it says anything with the word ASCII in it, that means your image is uncompressed ASCII (NetPBM type=3) and Tkinter will not like it:
board.ppm: Netpbm image data, size = 10 x 10, pixmap, ASCII text
if your file is correct, it will report rawbits (NetPBM type=6):
board.ppm: Netpbm image data, size = 10 x 10, rawbits, pixmap
If you want to convert from ASCII/P3 to binary/rawbits/P6, you could install ImageMagick with homebrew like this:
brew install imagemagick
Then convert like this:
convert board.ppm -compress lossless board.ppm

Tkinter PhotoImage error "encountered an unsupported criticial chunk type "iDOT""

I am trying to show an image on screen with python and tkinter, but when I run it, it gives an error in the PhotoImage object.
This is my code:
from tkinter import *
root = Tk()
photo = PhotoImage(file="devil.png")
label = Label(root, image=photo)
label.pack()
root.mainloop()
The image file is in the same folder as the .py file.
And it gives this error:
Traceback (most recent call last):
File "C:/Users/MyUsername/PycharmProjects/GUI test/home.py", line 5, in <module>
photo = PhotoImage(file="devil.png")
File "C:\Users\MyUsername\AppData\Local\Programs\Python\Python36-32\lib\tkinter\__init__.py", line 3542, in __init__
Image.__init__(self, 'photo', name, cnf, master, **kw)
File "C:\Users\MyUsername\AppData\Local\Programs\Python\Python36-32\lib\tkinter\__init__.py", line 3498, in __init__
self.tk.call(('image', 'create', imgtype, name,) + options)
_tkinter.TclError: encountered an unsupported criticial chunk type "iDOT"
Does anyone know how to fix this?

The chunk type of image you're using, 'iDOT', is not a registered PNG chunk. So, you should replace the image with an appropriate one.
This can help you understand what actually error is about

_tkinter.TclError: bitmap "pyimage2" not defined

I want to display an icon on a menu bar, so using this information, I coded this:
img = Image.open("help.png")
menubar.add_cascade(label="Help",menu=helpmenu,bitmap=ImageTk.PhotoImage(img))
I got this error:
Traceback (most recent call last):
File "mine.py", line 67, in <module>
m.menus(root)
File "mine.py", line 55, in menus
menubar.add_cascade(label="Help",menu=helpmenu,bitmap=ImageTk.PhotoImage(img))
File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 2699, in add_cascade
self.add('cascade', cnf or kw)
File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 2696, in add
self._options(cnf, kw))
_tkinter.TclError: bitmap "pyimage2" not defined
How to fix this ?

To display a PhotoImage you should use the image attribute, not bitmap.
You can also simply open an image file directly using ImageTk.PhotoImage(file='...')
So you can use the following code to display your image in the menu:
img = ImageTk.PhotoImage(file="help.png")
menubar.add_cascade(label="Help", menu=helpmenu, image=img)
